错误TS2304：将ng-bootstrap添加到TypeScript的Angular2快速入门时找不到名称'NGB_PRECOMPILE'

我正在尝试按照https://ng-bootstrap.github.io/#/getting-started上的说明将ng-bootstrap添加到Angular2的TypeScript快速入门中。当我做npm启动时，它给了我错误TS2304找不到名称'NGB_PRECOMPILE'。错误TS2304：将ng-bootstrap添加到TypeScript的Angular2快速入门时找不到名称'NGB_PRECOMPILE'

app.component.ts

import { Component } from '@angular/core'; 
import {NGB_DIRECTIVES} from '@ng-bootstrap/ng-bootstrap'; 
import { TasksComponent } from './tasks.component' 

@Component({ 
    selector: 'my-app', 
    directives: [ TasksComponent, NGB_DIRECTIVES ], 
    precompile: [ NGB_PRECOMPILE ], 
    template: `<h1 class="header">{{title}}</h1> 
     <tasks></tasks>`, 
    styles: [` 
     .header { 
      background: #999999; 
      border: 2px solid #444444; 
     } 
    `] 
}) 
export class AppComponent { 
    title = 'To Do List - Alaska'; 
}

main.ts

import { bootstrap } from '@angular/platform-browser-dynamic'; 
import { AppComponent } from './app.component'; 
bootstrap(AppComponent);

和依赖于package.son

我写的代码如下网站上的一步一步的指示：https://github.com/ng-bootstrap/ng-bootstrap。但是，底部列出的部分显示了组件的整体外观，并且在导入中列出了NGB_DIRECTIVES和NGB_PRECOMPILE，而分步说明却没有。这是我没有完全阅读代码的错误。

import {Component} from '@angular/core'; 
import {NGB_DIRECTIVES, NGB_PRECOMPILE} from '@ng-bootstrap/ng-bootstrap'; 

@Component({ 
    selector: 'app', 
    directives: [ NGB_DIRECTIVES ], 
    precompile: [ NGB_PRECOMPILE ], 
    templateUrl: './app.html', 
}) 
export class App { 
    ... 
}

修复了错误TS2304找不到名称'NGB_PRECOMPILE'。但是，我仍然无法在应用程序中获得引导程序。

你将它添加到您的systemjs.config.js文件？

//map tells the System loader where to look for things 
    var map = { 
    ... 
    '@ng-bootstrap/ng-bootstrap': 'node_modules/@ng-bootstrap/ng-bootstrap' 
}; 

    //packages tells the System loader how to load when no filename and/or no extension 
    var packages = { 
...  
'@ng-bootstrap/ng-bootstrap': { defaultExtension: 'js', main: 'index.js' } 
    };

感谢您的回复。我没有把代码放到那个文件中，但是我的错误在我的答案中得到了澄清。当你回应时，我再次看着它，所以谢谢你的回应，因为我仍然无法获得bootstrap的工作，这可能会有所帮助。 – ryegrammer
